A low cost valve and system for automated ebb and flow irrigation utilizes a collapsible sleeve to control fluid flow direction. No external power, moving parts, or floats are needed to operate the valve, resulting in improved reliability, low operating cost, and minimal need for maintenance. The valve operates using feed pressure to close the drain when hydroponic nutrient solution is pumped into the cultivation chamber. The valve drains automatically once the pump is stopped, usually by means of a timer, and the spent hydroponic solution is recovered. The fill/drain cycle is repeated as needed to keep the plants moist, yet not waterlogged.
